Tell whether the graphs of the two equations are parallel
(24) y = 8x-3 , 8x + y =3
(25) 2x + y = 5 , -6 + 2x = y
(26) 2x + y = 5 , y = 0.5x - 3
(27) y = -0.6 + 2 , 5y + 3x = 8
(28) 8x + 3y = 9 , 3y - 4 = 8x
(29) 10x + 2y = 7 , 5x - y = 6

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
